Holography is a vital tool used in various applications from microscopy, solar energy, imaging, display to information encryption. Generation of a holographic image and reconstruction of object/hologram information from a holographic image using the current algorithms are time-consuming processes. Versatile, fast in the meantime, accurate methodologies are required to compute holograms performing color imaging at multiple observation planes and reconstruct object/sample information from a holographic image for widely accommodating optical holograms. Here, we focus on design of optical holograms for generation of holographic images at multiple observation planes and colors via a deep learning model, the CHoloNet. The CHoloNet produces optical holograms which show multitasking performance as multiplexing color holographic image planes by tuning holographic structures. Furthermore, our deep learning model retrieves an object/hologram information from an intensity holographic image without requiring phase and amplitude information from the intensity image. We show that reconstructed objects/holograms show excellent agreement with the ground-truth images. The CHoloNet does not need iteratively reconstruction of object/hologram information while conventional object/hologram recovery methods rely on multiple holographic images at various observation planes along with the iterative algorithms. We openly share the fast and efficient framework that we develop in order to contribute to the design and implementation of optical holograms, and we believe that the CHoloNet based object/hologram reconstruction and generation of holographic images will speed up wide-area implementation of optical holography in microscopy, data encryption, and communication technologies.

A development tool for design and analysis of MEMS based EM energy scavengers Turkyilmaz, Serol; Külah, Haluk; Muhtaroglu, Ali (2010-12-01) This paper presents a development tool for estimating the performance of an electromagnetic (EM) vibration-to-electrical MEMS energy scavenger for low power mobile computing and wireless sensor applications. The tool takes design and excitation parameters as input, and estimates output voltage waveforms and power levels. It has been correlated against validation data, and used for early evaluation and design of new MEMS modules, which could not be optimized using off-the-shelf design packages. The tool was ...
A Randomized Scheduling Algorithm for Energy Harvesting Wireless Sensor Networks Achieving Nearly 100% Throughput Gül, Ömer Melih; Uysal, Elif (2014-04-09) This paper considers a single-hop wireless network where a fusion center (FC) collects data from a set of m energy harvesting (EH) sensors. In each time slot, k of m nodes can be scheduled by the FC for transmission over k communication channels. FC has no knowledge about the EH processes and current battery states of sensors; however, it knows the outcomes of previous transmission attempts. Also, battery leakage is ignored since it is very small. The objective is to find a low complexity scheduling policy ...
A feasibility study for controlling self-organized production of plasmonic enhancement interfaces for solar cells Borra, Mona Zolfaghari; Gullu, Seda Kayra; Es, Fırat; Demircioğlu, Olgu; Günöven, Mete; Turan, Raşit; Bek, Alpan (Elsevier BV, 2014-11-01) The decoration of metal nanoparticles (MNPs) by the self-organized mechanism of dewetting is utilized as a suitable method for plasmonic interface integration to large area full-scale solar cell (SC) devices. Reflection measurements are performed on both flat and textured silicon (Si) SCs in order to investigate the local plasmonic resonances of the MNPs. The effects of particle size and thickness of silicon nitride (Si3N4)anti-reflection coating layer are investigated by reflection measurements and the shi...
A Graph Based Big Data Model for Wireless Multimedia Sensor Networks Küçükkeçeci, Cihan; Yazıcı, Adnan (2016-10-08) Wireless multimedia sensor networks are of interest to researchers from different disciplines and many studies have been proposed in a wide variety of application domains, such as military surveillance systems, environmental monitoring, fault monitoring and distributed smart cameras in the last decade. In a wireless sensor network, a large number of sensors can be deployed to monitor target areas and autonomously collect sensor data. This produces a large amount of raw data that needs to be stored, processe...
The data acquisition and calibration system for the ATLAS Semiconductor Tracker Abdesselam, A.; et. al. (IOP Publishing, 2008-01-01) The SemiConductor Tracker (SCT) data acquisition (DAQ) system will calibrate, configure, and control the approximately six million front-end channels of the ATLAS silicon strip detector. It will provide a synchronized bunch-crossing clock to the front-end modules, communicate first-level triggers to the front-end chips, and transfer information about hit strips to the ATLAS high-level trigger system. The system has been used extensively for calibration and quality assurance during SCT barrel and endcap asse...
